AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers 37
RouterOS v3 Configuration and User Guide
radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest
amount of other networks detected, if no radar is detected in this channel for 60 seconds, the AP starts
to operate at this channel, if radar is detected, the AP continues searching for the next available channel
which is with the lowest amount of other networks detected
disable-running-check (yes | no; default: no) - disable running check. If value is set to 'no', the router
determines whether the card is up and running - for AP one or more clients have to be registered to it,
for station, it should be connected to an AP. This setting affects the records in the routing table in a way
that there will be no route for the card that is not running (the same applies to dynamic routing
protocols). If set to 'yes', the interface will always be shown as running
disconnect-timeout (time; default: 3s) - time since the third sending failure ( 3*(hw-retries+1) packets
have been lost) at the lowest datarate only (i.e. since the first time on-fail-retry-time has been
activated), when the client gets disconnected (logged as "extensive data loss")
frame-lifetime (integer; default: 0) - frame lifetime in centiseconds since the first sending attempt to
send the frame. Wireless normally does not drop any packets at all until the client is disconnected. If
there is no need to accumulate packets, you can set the time after which the packet will be discarded
0 - never drop packets until the client is disconnected (default value)
frequency (integer) - operating frequency of the AP (ignored for the client, which always scans through
its scan list regardless of the value set in this field)
frequency-mode (regulatory-domain | manual-tx-power | superchannel; default: regulatory-domain) -
defines which frequency channels to allow
regulatory-domain - use the channels allowed in the selected country at the allowed transmit power
(with the configured antenna-gain deducted) only. Also note that in this mode card will never be
configured to higher power than allowed by the respective regulatory domain
manual-tx-power - use the channels allowed in the selected country only, but take transmit power
from the tx-power settings
superchannel - only possible with the Superchannel license. In this mode all hardware supported
channels and transmit power settings are allowed
hide-ssid (yes | no; default: no) - whether to hide ssid or not in the beacon frames:
yes - ssid is not included in the beacon frames. AP replies only to probe-requests with the given ssid
no - ssid is included in beacon frames. AP replies to probe-requests with the given ssid ant to 'broadcast
ssid' (empty ssid)
hw-retries (integer; default: 15) - number of frame sending retries until the transmission is considered
failed. Data rate is decreased upon failure, but if there is no lower rate, 3 sequential failures activate on-
fail-retry-time transmission pause and the counter restarts. The frame is being retransmitted either
until success or until client is disconnected
interface-type (read-only: text) - adapter type and model
mac-address (MAC address) - Media Access Control (MAC) address of the interface
master-interface (name) - physical wireless interface name that will be used by Virtual Access Point
(VAP) interface
max-station-count (integer: 1..2007; default: 2007) - maximal number of clients allowed to connect to
AP. Real life experiments (from our customers) show that 100 clients can work with one AP, using traffic
shaping
mode (alignment-only | ap-bridge | bridge | nstreme-dual-slave | station | station-pseudobridge | station-
pseudobridge-clone | station-wds | wds-slave; default: station) - operating mode:
alignment-only - this mode is used for positioning antennas (to get the best direction)
ap-bridge - the interface is operating as an Access Point
bridge - the interface is operating as a bridge. This mode acts like ap-bridge with the only difference
being it allows only one client
nstreme-dual-slave - the interface is used for nstreme-dual mode
station - the interface is operating as a wireless station (client)
station-pseudobridge - wireless station that can be put in bridge. MAC NAT is performed on all traffic
sent over the wireless interface, so that it look like coming from the station's MAC address regardless of
the actual sender (the standard does not allow station to send packets with different MAC address from
its own). Reverse translation (when replies arrive from the AP to the pseudobridge station) is based on
the ARP table. Non-IP protocols are being sent to the default MAC address (the last MAC address, which
the station has received a non-IP packet from). That means that if there is more than one client that uses
non-IP protocols (for example, PPPoE) behind the station, none of them will be able to work correctly
station-pseudobridge-clone - similar to the station-pseudobridge, but the station will clone MAC
address of a particular device (set in the station-bridge-clone-mac property), i.e. it will change itsown
